You don't do prisoner exchanges because of the valuable contributions of that agent, you do prisoner exchanges to ensure future contributions by other agents.
>I also doubt the quality of the optics in Russian satellites.
They're just fine. What kind of quality do you think they need to hit a power plant with a missile? Most of their missiles aren't that precise anyway.
There's only an extremely limited set of circumstances where drone footage of power infrastructure could be useful.
Doesn't Leica have a reputation for world-beating optics?
Uh, why? I can understand doubting the electronics in their satellites, but the mirrors? Why do you think Russia can't polish mirrors?
Yeah, but physics isn't. Good resolution requires large mirrors. Large mirrors require large satellites. These aren't cubesats we're talking about; optical American spy satellites have 2.4 meter wide mirrors and are more than 10 meters long. The only non-US/Chinese/Russian rocket that can launch such a satellite in principle is the Ariane 5, but AFAIK they don't fly that to polar orbits.
In any case, not many people have the equipment laying around to make such large mirrors, or the expertise, or a stockpile of such mirrors. Russia likely has all three, or certainly once did.
